Robyn had just fled another crime scene.

FINN

Finn rang the bell again. He imagined Judd Archer inside, trying to calm a suddenly panicked Robyn – he checked his notes again – Peltier.

He stepped back for a better look at the house. Small, maybe two bedrooms. A decent neighborhood. Not good, but decent.

He should buy a house.

He'd been saying that for three years, but hadn't so much as skimmed a real estate page. He supposed that unless the perfect house magically appeared – For Sale sign on the lawn, Realtor at the door – he'd never get further than wishful thinking.

Apartment living wasn't for him. The endless trekking up the stairs or elevator. The noisy, nosy neighbors. Watching his money evaporate with nothing to show for it. Finn told himself he didn't have the time to house-shop, but the truth was that he didn't dare invest his life savings in a place where he might discover he wasn't the sole tenant.

Though Finn rarely saw ghosts outside a crime scene, it did happen, especially in places where he spent a lot of time. Twice he'd had spectral roommates.

The first one, he'd only glimpsed. He'd walk into a room and see the faint outline of a middle-aged woman, who always faded before he could get a better look. She hadn't scared him, but it was like reading with someone hovering over your shoulder. He could always sense her there, was always waiting for her to interrupt him.

The second one he had seen. Another woman, this one young, lying naked in the claw-foot bathtub. Not such a bad image... if she hadn't slit her wrists and looked as if she'd been in that tub for weeks. Finn had worked a few floaters in his time, and it wasn't a vision he wanted to see first thing every morning. He'd moved out within two weeks, and lost a big chunk of cash.

That second one still bothered him. Even on crime scenes, the ghosts he saw appeared whole and unharmed as they'd looked before their death. And the drowned woman had never moved, never spoken, never opened her eyes.

He'd wondered whether there'd been something he was supposed to have done. He'd researched the case, but never found anything. Just an anonymous death in an anonymous city.

Finn rang the bell a third time, then leaned forward, straining to hear a struggle or an argument. Archer said Peltier wanted to talk to him, but she could have changed her mind.

He should have brought backup. Under any other circumstances, he would have, but here he'd figured he already had it in Judd Archer. He didn't know the guy, but he'd heard his story – ex-cop turned celebrity bodyguard. Not true.

Archer had never left the force. He was undercover, trying to break into an organized crime ring through their purported relationship with some glitterati types. If things went bad in there, Archer would be Finn's backup.

Finn wondered whether Portia Kane was one of those celebs who supposedly liked hanging out with young mobsters. If so, that could answer some questions about her death. And this Peltier... Jansen said Peltier hadn't been with Kane long. She could be a plant, maybe a mobster's –

Finn shook his head. He was daydreaming again. One foot in this world, one foot in the next, his mother used to say.

He gave the doorknob a tentative turn. It opened. When Peltier woke Archer, relocking had probably been the last thing on his mind.

Finn called a hello. No one answered. He took out his gun and started forward.

The lights were on in the front hall and what looked like the kitchen beyond. Finn stepped into the kitchen and saw Archer standing over a body.

Finn's gaze flicked from the body to the figure above it. The ghost glanced up. Their eyes met.

"Shit," Finn whispered, and looked away.

Gun poised, Finn began searching the house for Archer's killer. He made it through the front rooms and was heading to the bedrooms, when a voice behind him said, "You want some help with that?"

Finn hesitated then, not glancing back, continued on.

"I know you can see me," Archer said, stepping in front. "You looked right at me in the kitchen. You can hear me, too, or you wouldn't have paused when I spoke."

Finn lifted a finger, telling Archer to wait until he'd finished his sweep. Insensitive but necessary. He'd once been so engrossed in questioning a victim's ghost – and keeping the rest of the team from overhearing – that he'd missed the killer hiding behind the sofa. The only thing that saved him from a bullet was the guy's shock when he leapt out to discover the detective was talking to thin air.

So Finn continued his search, with Archer tagging along, calm and focused, as if he was just another officer on the scene. Finn met two kinds of ghosts: those too distraught to give a coherent account and those whose accounts were eerily coherent. They knew they were dead; it just hadn't sunk in yet.

They'd finished searching the spare room when Archer, heading out the door, went to pull it farther open for Finn, and his fingers passed right through. He stared at them, then did it again.

"Ah, shit." Archer's shoulders slumped.

"I'm sorry," Finn said.

Archer nodded. He kept staring at his hand, and Finn resisted the urge to pepper him with questions, knowing the clock was ticking and at any moment Archer could vanish.

"So what happens now?" Archer said. "Am I stuck here? A ghost?"

"You'll be taken to the afterlife." Finn had no idea where ghosts went when they disappeared, but it was something after life, so he wasn't lying.

"I guess this is how you solve all those cases, huh?" Archer managed a small smile. "Insider information?"

"It helps. Can you tell – ?"

He stopped, remembering Archer's body lying on the kitchen floor. The longer he waited to call in the death of an officer, the more fast talking he'd have to do to explain the delay... and fast talking really wasn't his thing.

While he called for assistance, he asked Archer to explain what happened. Unfortunately, this was one of those times when having access to the most important witness wasn't going to help. Archer hadn't seen who'd killed him.

He'd been making coffee and, the next thing he knew, he was standing over his body.

"Did you hear anything?" Finn asked after he'd hung up.

"Nah. I was grinding beans." He gestured to a small appliance on the counter. "Yes, I grind my own. I had a girlfriend who got me hooked. Anyway, those things make a helluva racket." He paused. "I may have heard the shot, but it was too late."
